The conventional approach to solvent extraction is the batch method. Early work with this method was hampered by the low concentration of the compounds present and the relative insensitivity of the methods of characterization. Thus lipids and hydrocarbons have been separated from seawater by extraction with petroleum ether and ethyl acetate. The fractionation techniques include column and thin-layer chromatography with final characterisation by thin-layer chromatography, infrared, and ultra-violet spectroscopy and gas chromatography. Of these techniques, only gas chromatography is really useful at levels of organic matter present in seawater. With techniques available today such as glass capillary gas chromatography and mass spectrometry, much more information could be extracted from such samples [20]. [Pg.366]

Xie [39] determined trace amounts of chlorophenols and chloroguaiacols in marine sediments collected off the Swedish coast. The compounds were desorbed from sediment surfaces by a mixture of acetic anhydride and hexane, after buffering with O.lmol L 1 sodium carbonate. The optimal pH was achieved by a 1 4 ratio of buffer to acetic anhydride. The acetylated extracts were analysed by glass capillary gas chromatography with electron capture detection. The recoveries, at the pg kg-1 level, ranged from 85-100% with standard deviations of 4-11%. [Pg.171]

Gas Chromatographic Analysis. We used temperature programmed glass capillary gas chromatography to separate PCB residues. Use of an electron capture detector required an efficaceous sample cleanup for isomer quantitation (27). These combined techniques offered enhanced separations and enabled us to identify and quantitate individual PCB constituents (jL> 27). Schwartz (27) separated more than 100 constituents from a 1 1 1 1 mixture of Aroclors 1242, 1248, 1254, and 1260. [Pg.197]
